Greece’s electricity retail market is entering a consolidation phase that analysts believe will result in four dominant suppliers. Smaller retailers with market shares just above 10 percent are seen as the most likely candidates for acquisitions or market exits as merger and acquisition activity accelerates.
Public Power Corporation (PPC) remains the market leader with a share of about 47 percent and is expected to retain the top position, even though its share is projected to drop below 45 percent in 2026.
Metlen is firmly positioned in second place. Following two years of acquisition-led expansion, the company plans to continue buying competitors, aiming to grow its share from around 22 percent today to approximately 30 percent by the end of 2026.
The third major player is expected to be the combined Heron-NRG entity after their merger.
Helleniq Energy, which currently holds 5.78 percent of the market after taking full ownership of Elpedison, lags behind the leading group but aims to double its share by 2026 in an effort to narrow the gap.
